I am attempting to write a 3d graphics program.  I mean REAL three
d here.  I have a homebrewed set of goggles (X-specs for the Amiga) that
I modified to work with the IBM serial port.  They flip everytime
I set DTR or RTS high and low.  I need to be able to flip them the
same time the monitor swaps...is this possible?  I know the Amiga 
somehow does this (although I think it relies on the interlacing).

During the retrace I also have to swap video pages...is this possible?
In other words, an image on page 0 will have a picture that is slightly
offset from the image on page 1.  Swapping pages at the same time that
the glasses swap shutters would produce a 3d effect...I know this
works since I've done in character mode, where speed isn't as larage
a concern.

Any info in C would be appreciated.
